MACHINE FOR MIXING ASPHALT. v No. 295,707. Patented Mar. 25, 1884 W zfnesses'." A I J'Zwenfar:

' To allwhom it may 00100827141 a Be it known that I, GEORGE WINDING, of Milwaukee in the county of Milwaukee, and in the State of Wisconsin, haveiuveuted ceri u that the following is a full, clear, and exact description thereof. i l i u I i i ,Myinventionrelatestomachinesformixing asphalt; andit consists in certain peculiarities of, construction, as will be more any set forth hereinafter. i l 2 In the drawings, Figure l is a vertical cen tral longitudinal, section of my devices 2 is auelevation of one end, and Fig. 3an

elevation of the other end, of the said machine. Q: R Ais thelower partofmydevicaand contains Qthe grate orffire-bed "B, supplied with fuel through door b and also serves. asa support u for the stationary cylinder 0, within which the asphalt, 850., is placed tobe 'n eltedand mixechthe said material being inserted through thedoors D D, hinged on opposite sides of the a; GEORGE WINpiivGfor MILWAUKEE, isconsin. I

a s-lemma forming part of Letters Patent No. 295,707, dated March 25, 1884-.

"Applioation filed January 2,1684 (No model.)

tain new and ,useful Improvements iuM-achines for lllixing Asphalt; and Idol hereby declare upper jpartof, thelsaid. cylinder.

1 E is the stirrershaft, extending longitudinally through the center of the cylinder (J, and supported in suitable bearings, e 6, outside of the same, rising froui the top of the furnace part A, and to this shaft are secured, by keys or setscrews, the shanks of the stirrereblades E E. i i a Gis the outlet for the mixed and melted asphalt, &c., and consists of a pipe leading from the lower part of the front end of the cylinder 0, out through the front face of the furnace part A,and which is closed bya suitably-pivoted gate, 0, with shank scoured back of .a

stop, 0. Above this outlet-pipe the furnace partAeXtends outward and forward, as at A, to receive the Smokestack A which latter may be provided with a suitable damper, as at a. Each side of the furnace part A is pro vided with a series of openings or coolingports covered by pivoted gates etc, so as to regulate the temperature at any part ofthe furnace at will, while the temperature of the mixing-cylinder O is regulatedby means of a ventilating-pipe, G on top, controlled by a damper, c".

On the endof the shaft E that projects out through the rear end of the cylinder, there is secured a worm-wheel, F, and below this is a U D STAT-ES PATENT OFFICE? 3 y trough, G, which is kept filled with greasy water, so that the woriu wheel, as itrevolves,

will'pass through the said greasy water, and

thus be kept cool, as well as be. constantly lul bricated; and when the water becomes too hot it may be drawn oifby means of cock 9, and a fresh 'supply of greasy water be substituted,

therefor. u l l i u a i H is a shaft bearing alworm whiclrmeshes with the WOPm-WhQQl F, and supported in bearings h h, secured to and rising from the, \furnace part A, and this ,shaftalso bears at i is communicated, througha belt, 1', to revolve l said shaft, and thence, through thewormaud oneen'd the pulleyI, bymeans of which power its geanwheel, to the stirrer-shaft E andtstir' rersE. a a v a u a i The operation of my device will be apparent of separate melting and handmixing, audit is extremely useful in laying road-beds or side- Walks, in roofing, and wherever asphalt or similar material is to be used. l u

, Having thus described myinventiomwhatI claim,

and desire to secure by Letters Patent, T

combination, with a stationary cylinder and from the foregoing description of its construction, and by its use agreat saving int1me,,la bonan d expense is effected over theold method 1. In a machine formixing asphalt, &c.,the

furnace, of a horizontal stirrer-shaft having stirring-blades attached thereto, a worm shaft,

, an exterior water-trough, and a worm-wheel adapted to revolve in said trough, substantially as set forth. 2. In a machine formixing asphalt, &c.,the

combination of the stationary cylinder 0, haviug ventilating-pipe G, with damper c and outlet pipe 0, horizontal shaft E, with stirrers E, attached thereto, and furnace A, below the cylinder, having fire-bed and series of coolingports controlled by gates a a, substantially as set forth. a

--In testimony that I claim the foregoing I have hereunto set-my hand, at Milwaukee, in the county of Milwaukee and State of 'W'iscousin, in the presence of two witnesses.
